SPECIFICATION forming part of Letters Patent No. 657,287, dated September 4, 1 906.

Application filed January 4. 1900. Serial No. 352. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES J. J oHNsoN, a citizen of the United States, residing at Paso Robles, county of San Luis Obispo, State of California, have invented an Improvement in Baling-Presses; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to improvements in baling-presses, and is especially applicable to that class known as horizontal continuous presses.

The object of my invention is to provide for means by which the opening and closing of the doors and the various operations of the machiueare performed mechanically and the hand-labor is reduced.

My invention consists in mechanism by which the various operations of opening and closing the press are performed by the contin uous operation of the horse-power or other motor applied at the proper intervals to prosection through the baling-box on line y y of Fig. 4. Fig. 4 is a similar section on line a; o:

of Fig. 3, the side door being removed.

The main frame 1 of my press is mounted upon wheels 2, which serve to conveniently transport it from place to place. Adjacent to or above the wheels at one end is mounted the circular plate or disk 3, to the shaft of which is connected the sweep 4, and to this sweep the team is attached for the purpose of communicating power to rotate the shaft 5 and with it the connected parts. It will be manifest that other and well-known forms of motors or drivers may be used instead of the sweep'without departing from the spirit of my invention, the object in any case being to rotate the shaft at a rate of speed which will allow the material to be baled to be introduced when the press is opened, thedoors to be closed, the follower to be advanced to' press the charge of material,the doors opened, and the follower retracted to receive a new charge, the intervals between the various operations being so regulated that they will follow each other with uniformity. The pressbox 6 is situated at the opposite end of the supporting-frame, as shown, and the opera tious carried on therein are effected by a plunger-beam 7, which reciprocates the follower, and by shafts 8 and 9, which are actuated to alternately open and close the doors of the press.

The plunger-beam is connected at one end with he plunger or follower 10, and at the other end it has mounted upon it an antifriction roller or rollers 11, which are acted upon by cams 12, fixed to and carried by the circular disk 3, through which the power is transmitted to rotate the cams, so that they alternately push the beam 7 forward and move the follower through the press aftera charge of material has been placed therein. When this movement has been completed, the ends of the cams passing the rollers 11 release the plunger-beam, and this is returned to its normal position by a spring or springs 13, suitably arranged and connected for the purpose. The plunger-beam forms a straight line between the pointof application of power through the rollers 11 and the follower 10. A plate 14, fixed to the plunger-beam, curves out of line of the plunger-beam and then extends along parallel with the line of-the plunger-beam. It is slotted as shown at 15, so that the slot fits over the shaft 5 and is slidable with relation to the shaft when the plunger-beam is reciprocated. This slotted plate serves as a guide to keep the plungerbeam in line when being actuated by the cams.

Projecting downwardly from the plate or disk 3 are lugs or projections 16 and17, the lugs 16 being nearer to the periphery of the disk and the lugs-17 interior to the line of the projection 16. These lugs are at different distances from the shaft 5 and are so spaced that the lugs 17 stand between the lugs 16. The lugs 16 act upon a rocker-arm 18, fixed upon the end of a shaft 8, and the lugs 17 correspondingly act upon a rockerarm 19 on the end of a shaft 9, so that during the rotation of the diskone of the lugs 16 will act upon the rocker-arm 18 and rotate the shaft 8 a partial revolution through mechanism connected with the opposite end of this shaft and to be hereinafter described. This operation will close the doors of the press just previous to the action of the cam upon the plunger-beam, which advances the follower to compress the charge. thus inclosed. As the driving-shaft and disk continue their rotations one of the lugs 17 will arrive at the point where it acts upon the rocker-arm 19 and rotates the shaft 9, and through mechanism upon the opposite end of said shaft the doors, having been previously released from their latches, will be opened in readiness for another charge. At or about the instant of opening the doors the plunger-beam will be released from the end of the cam and will be retracted by its spring 13, thus bringing the follower with-it. These operations take place twice with each revolution of the disk.

The press-box 6 consists of a stout frame having a bottom .and one side. The top is formed of a hinged door 20 and the other side by a door 21, hinged at the bottom, so as. to open outwardly when the door 20, which is hinged at the opposite side, opens upwardly. The side door 21 hasa slidable extension 22 movable upon its face, as shown, and this extension is forced outwardly when the door is released by means of a spring 23. tension serves as a guide when the door has been opened and tilted outwardly for the reception of the material to be pressed, sothat any considerable quantity of material placed in the press will be guided into the inner portion of the box, and when the top door closes down it first contacts with the end of the sliding extension 22 and forces it down to coincide in length with the main portion of the door 21. At the same time the door 21 is pushed inwardly and the action of the two doors would be to partially compress the loose mass of material which has been placed in the. press in readiness to be further compressed by the action of the follower.

24 is a circular yoke, having its end fixed to the sides of the press-box above the plungerbeam 7, and a rod 25 connects the yoke with the shaft 5 above the cams 12, so as to unite the two and by its tension prevent their being pulled apart by the strains brought upon them. The plunger-beam 7 is made much deeper at the end adjacent to the press-box, as shown at 7, so as to provide a deep bearing against the follower. Upon the top it is ex tended upward, as shown at 26, and this part abuts against the inside of the yokev 24 when the plunger-beam is retracted by its spring, thus acting as a stop to limit the movement of the follower in this direction.

The movements for opening and closing the doors by the action of the, shafts 8 and 9 will be as follows: The top'door 20 is connected by a rod 27 with a crank 28. Upon the same shaft with this crank 28 is formed another crank 29, and this is connected by a rod 30 with a lever-arm 31, which is fulcrumed to some part of the press-frame, as shown at 32.

This 6X-.

The lever 31 is connected by a rod 33 at one side of the fulcrum 32 with a rocker-arm 34 upon the shaft 8. From the other side of the fulcrum 32 of the lever 31 a rod 35 is connected with the rocker-arm 36 on the crank-arm 9. When one of the lugs 16 of the drivingdisk 3 engages with the rocker-arm 18 of the shaft 8, it rocks this shaft and with it the rocker-arm 34 at the opposite end, which, acting through the connecting-rod 33, lever 31, rod 30, cranks 28 29, and rod 27,,willclose the top door 20. By a like movement the rocker-arm 36, which is connected with a crank-shaft 37, journaled upon the side of the press-frame, turns this crank-shaft, and by connection 37 between it and the door 21 the latter will also be closed. When these doors are thus closed, they are locked in place by spring-actuated bolts, the bolt 40 serving to lock the top door and the bolt 41 in a similar manner locking the side door, and they are thus held until the follower 10 has been advanced by the action of the cams upon its plunger-beam, as previously described. This follower carries a pin 42 upon one side and located beyond the edge of the follower, as shown in Figs. 3 and 4.

The door 21 has a channel 43 made along its inner face in the line of movement of the pin 42, so that the pin is carried along this channel when the follower is advanced and out of theline of the mass of material which is being compressed by the follower. This pin 42 acts to release the latches of the two doors when the follower has reached the end of its stroke as follows: The pin 42 contacts with the bottom of a-centrally-fulcrumed lever 44, and thus pushes the bottom outwardly.

The lever turning about its fulcrum at 45 the upper end will correspondingly move inwardly and acting against a second lever 46, which is fulcru med at the bottom, as shown at 47, this lever 46 is moved inwardly.

In line with the latch-bolts 40 and 41 are pins 48, which fit and are slidable in corresponding holes in line with the latch-bolts 40. The lever 46 contacts with the outer ends of these pins when it is pushed inwardly, as before described, and through the pins the latches 40 and 41 are forced back until they are disengaged, and the doors can then be opened. The locking-pins 40 and 41 project from each side of their respective doors, and their inner or adjacent ends are connected with a rotary disk 49 in such a manner that when the disk is turned in one direction the lockingbolts will be advanced and when turned in the opposite direction they will be retracted. A spring presses against this locking-disk in such a manner as to normally force the locking-bolts outward, and they are thus always in readiness to engage with their sockets when the doors have been closed; but when the push pins 48 have been forced against the bolts to retract them they rotate the disk 49 against the pressure of the spring 50 until the bolts are released from their sockets and the doors unlocked, so as to permit them to be opened when one of the lugs 17 of the disk 3 acts upon the rocker-arms 19 of shaft 9. WVhen this occurs, the shaft 9 is rotated and through the rocker-arm 36 and the connecting-rod 35 it acts upon the lever 31, and through the connecting-cranks and rods the door 20 will be opened after its release. In the same manner by means of the connecting-rod 52 and the cranks and rods connecting with the side door 21 the latter will also be opened in readiness to receive another charge of material. As the material is thus placed in the pressbox and advanced by the reciprocations of the follower it passes out into the extension portion beyond the pressbox. This extension consists of a framework 53, havinga permanent bottom plate and open sides to allow access for the purpose of tying or securing the bale-sections and an adjustable top 54:. This top plate is made of metal sufficiently elastic, secured at the inner end, and at the outer end it is adjusted and movable by screws 55, passing through the top of the outer end of the frame, so that by turning these screws or by an equivalent actuating device this plate maybe bent downwardly and thus contract the end opening through which the finished bales are discharged. The object of this contraction is to increase the pressure necessary to force the bales out through this opening,andthisinsuresatighter compression of each bale. The amount of pressure can be correspondingly reduced by retracting the screws 55 and allowing the plate 54 to move outwardly to open up the discharge. Asthe follower presses the material from the press-box into this extension the usual spring-pressed dogs or catches 56 are forced inwardly and engage the mass which has been pushed out by the follower, so as to prevent its returning by its own elasticity. These catches or holders being common to this class of press, I do not further illustrate or describe them at this point.

57is aspring-pressed apron or plate extending downwardly at the upper part of the exit from the press-box.

In order to separate the pressed material to form bales of the proper size and to provide for tying or fastening these bales as they are completed, division-blocks 58 are inserted in front of the follower whenever a sufficient amount of material has been compressed to form a bale, and when the follower is again advanced this block is pushed along with it, and passing outside of the catches or holders, Will be retained by them, and thus separate the exterior compressed material from the next charge which is placed in the press. These division-blocks have transverse grooves or channels 59 made in them for the reception of the tying cords or wires, which, being easily pushed through these channels,are afterward drawn tight around the sections between any two of the blocks and their ends secured together, so as to complete the bale. The continued reciprocations of the follower force each bale out through the contracted end previously described, and the operation is thus continued at will.
